TILE-LAYING MACH'iNE.

SPECIFICATION forming part of Letters Patent No. 295,119, dated March 11, 1884.

' Application filed September 10, 1883. (No model.)

To 0555 whom it may concern:

Be it known that we, Jnssn THOilIAS Gnilvns and BENJAMIN F. BELT, of 0010, in the county of Story and State of Iowa, have invented a new and useful Improvement in Tile-Laying Machines, of which the followingisa full, clear, and exact description, reference being hadto the annexed drawings, forming part of this specification.

This invention relates to plows or machines for embedding draintiles in the surface of lands and the invention consists of the novel construction hereinafter described and claimed.

In the drawings, Figure l is a side elevation, and Fig. 2 is a plan view, of our improved Fig. 3 is a section on line a" a: of Fig. 1, and Fig. 4 is a perspective view of the coverer.

A indicates the main frame of the machine, and B is a supplemental frame arranged within the frame A, and pivoted thereto at its rear end. Near the center of frame B is secured the cutter-stock O, which has a V-shapcd edge, D, adapted to press the soil outwardly from its track. The cutter-blade E is connected to end of frame B, forming with said parts, approximately, an equilateral triangle. The bladell, which serves the double purpose of a cutter for dividing the soil, and a brace for supporting the stock (l, is provided with an arm, F, which extends up behind the lower part of the stock and through its upper end, while the lower part of the stock is grooved On this arm is hinged the V-shaped hollow shield G, which is fitted to the stock in such manner that the edges formed by the groove in the rear edge of the stock shall partially overlap the sides of theshield. Thesides of the shield are inclined in such manner as to form a nearlycontinuous plane surface with the sides of the V-shaped stock, so that the shield shall still further press the soil outwardly from the track to form a trench sufficiently large for the tiles. The shield G is made of sheet metal, and the sides are braced at the rear end by a fold or cross-plate, H. live prefer to form the plate H as the front end of a supplemental shield, I, in which the tile-trough J is arranged. In

such case the front end of the shield I is formed with grooves or cleats, into which suitable flanges at the rear edges of the two hinged plates forming the shield G are adapted to be inserted by first opening or spreading said plates apart, the resistance offered by the soil being sufficient to hold the parts together. The supplemental shield I is formed with its sides sloping inward toward the rear, to lessen friction with the sides of the trenclnwhile they serve to prevent any loose earth from falling tion, approximately, in the line of the trench,

and they intersect each other longitudinally in the trench. The object of the cutters is to cut the soil loose at the sides of the trench in such manner that the two slices which are thus formed on two inclines shall slide down against each other, and thus form a cover for the tiles and trench.

The frame A is provided with standards L and a cross-bar, M, which serves as a fulcrum for a lever, N, attached to the forward end of the frame 13 by a rod, 0. The lever is designed to hold the trench-forming device at any given position, according to the depth of trench required. The lever may be held by hand, or any well-known device suitable for the purpose may be employed.

\Vhat we claim is 1. The combination of the stock, the supporting-frame, the cutter-blade connecting the lower end of the stock with the frame, and having an arm extended up behind the stock, and the shield formed of two plates hinged to said arm,substantially as shown and described.

2. The combination, with a suitable frame, of the V-shaped stock inclined forward at its lower end, the cutter-blade connecting the lower end of the stock with the frame, and having an arm extended up behind the stock,

the shield formed of two plates hinged to said arm, the supplemental shield arranged between said plates and connected thereto, and having sides which incline toward each other at the rear, and the tile-trough secured to the stock, and supported in the supplemental shield; substantially as shown and described.

3. The frame K, having the \I-shaped blade K set with the planes of its sides or wings ex- 10 tended in a transverse direction approximately,in theline of the trench, and intersecting each other longitudinally in the trench, substantially as shown and described, and for the purpose set forth.
